BOX One 7-speed DH transmission

Box Components’ seven-speed DH groupset consists of a compact 11-24t cassette, short-cage rear mech and shifter. The sprockets slot onto a standard freehub and use 11-speed spacing. Forged construction means the rear mech should handle a pasting, and it has an adjustable clutch mechanism to stop your chain flailing. The shifter uses two levers, with dual-direction release. www.todayscyclist.co.uk
